Abortion at 7 weeks of pregnancy is usually not too harmful and most patients can recover as before, but some complications may occur in some patients. Abortion is the use of instruments directly into the uterine cavity, through the negative pressure suction, directly suction scraping out the intrauterine pregnancy. Abortion is directly operated by instruments, so it will damage the uterine lining to a certain extent. The surgery itself does not cause much damage, but because of this operation, there is a possibility of surgical complications, such as bleeding, infection, perforation of the uterus, uterine adhesions, etc. If there are complications, the subsequent treatment may lead to greater damage, such as uterine perforation of a large rupture, it is necessary to go into the abdominal cavity to explore. Regardless of post-operative recovery, abortion has a certain degree of damage to a woman’s body, and if there are no plans to have children for the time being, attention should be paid to contraception.
